Flag configuration can prevent refactoring

[nboldi]

In the package NineP, there is flag that should be specified but somehow it seems it isn't. The dependencies look like:

    if flag(bytestring-in-base)
      -- bytestring was in base-2.0 and 2.1.1
      build-depends: base >= 2.0 && < 2.2, binary >= 0.5.0.2
    else
      -- inbase 1.0 and 3.0 bytestring is a separate package
      build-depends: base < 2.0 || >= 3, bytestring >= 0.9, binary >= 0.5.0.2

In package timezone-series the flags are not configured good by default for the actual version of the time package
